Answer: The range is 
Explanation:
The parabola opens down, forming a "frowny face" in a way (just without the eyes). Or you can think of it as a hill or mountain. This means that the vertex (-3,-6) is at the top of that mountain. It's the highest point of that parabola.
The range is the set of all possible y values. We see that y = -6 is the largest it can get. So y = -6 or y is smaller than this. We would then write 
to describe all the possible y values.
Therefore, the range is
This translates to "y is a real number such that y is -6 or smaller".
So the second answer you wrote is close, but you forgot the "or equal to" portion of the inequality sign.
See below for a visual example of what's going on.
Answer:
C
Step-by-step explanation:
an arithmetic sequence is a sequence in which you use addition/subtraction in order to achieve each term. Choice A alternates between the negative and positive therefore you can tell that it's multiplying each time, and the same goes for D, those two are incorrect. B is incorrect because you cannot add/subtract a number each time to get the next term. C, if you attempt to find the difference between in each term in choice C you will succeed and find that each time you add 3/2 each time to get the next term.
Answer:
Obviously, Juan because he played less game last season and got the same amount of points so this season when he plays more games he would get more points than Neil
<em>There is no specific requirement in the question, but I'm assuming you need to compute the time needed for Alexis reach 1,000,000 Instagram followers</em>
Answer:
Step-by-step explanation:
<u>Exponential Growth
</u>
When the number of observed elements grows as the previous value multiplied by a constant ratio, we have exponential growth. The formula to model such situations is
Where 
is the initial value of f, 1 + r is the constant ratio, and t is the time expressed in half days (12 hours)
The initial value is 100 Instant followers, thus:
We need to know when the number of followers will reach 1,000,000. Setting up the equation
Simplifying by 100
Taking logarithms
Solving for t
periods of 12 hrs
Answer:
one quarter of the total number of students will be those who failed their exam.
Step-by-step explanation:
Three - fourths = those who passed the exam
one quarter will be those who failed their exam
From the total number of the students.
Let's make an example
40 students who take the exam.
3 over 4 students from the total number of 40 take the exam and the result is passed and it mean 30 students passed in the exam.
1 over 4 students take the exam and the result is failed and it mean 10 students failed in the exam.
4 minus 3 over 4 will get the answer 1 over 4.
Use 1 over 4 to multiple with the total number of the students and that how you will get the answer for those who failed in their exam.
